Fairlay does tick a lot of boxes and it depends a bit on a) what markets OP wants to bet and b) what is his average bet size, but it's not perfect as well.
You make a fair point. Fairlay's liquidity is great sometimes, but terrible some other times though it does satisfy almost all of op's conditions which is why I recommended it. The alternatives like Exbet etc are worse in comparison.
But its possible deposit and withdraw direct from hardware wallet - crypto bookie ? and the opposite ?
Obviously. You can send and receive BTC and other popular cryptocurrencies directly between the wallet and the bookie irrespective of whether you are using a software or hardware wallet.
